Irena Sendler created change by offering medicine and supplies. Irena brought food and medicine to the people in the Warsaw ghetto especially children. If it weren't for Irena bringing supplies then more people would've died. her and her friend Antori smuggled food and more medicine into the ghetto. The consequences were jail time. Or even death. The people in the ghetto got sick from hunger and/or from the unsanitary places they live in.
Secondly Irena related change by taking care of children. She took care of the children by helping them
escape. Irena changed their names to keep them from having a Jewish name and to owner the chance of them getting caught. She changed them to Christianity by teaching them the Lord's Prayer. This way if they got caught then they would recite the Lord's Prayer and get past.
Lastly Irena made a change by having a growth mindset. Irena went to jail but that didn't breake her because when she got out she still continued to help the children. While she was in jail she was wiped and beaten. She still wouldn't speak. Irena kept trying because she wanted to help more children.
Irena Sendler crated change because she offered medicine and supplies, she took care of children, and by having a growth mindset. If it weren't for Irena Sendler more kids would've died.
